The city of Venezia is absolutely indescribable. While I have been reluctant to visit tourist laden cities (with good reason, you get the worst food, pay the most for it and are often treated poorly to boot), Tommaso had a point when he says there is nothing like this city in all the world. And he's right.
You step off of the train and walk outside and immediately you stand before the canals of Venezia. From here the stream of tourists wisks you down the street, over countless bridges that cross the ever narrowing canals, all the while the three story buildings seem to close in above you as the streets become as narrow as the canals. The effect on the senses is stunning. If you can get past the crowds and the merchants eager to cheat you out of whatever may lie in your pockets, the city itself is a time portal. The irony is that the crowds have facilitated this upkeep, while deminishing the charm of the city at the same time.
Still, I must say, that Venezia is a place worth visiting, as it is indeed, one of a kind.
